METEREOLOGICAL STATION

WIND

The wind is caused by differences in the temperature of air masses. Wind speed is usually measured in Knots (an abbreviation for nautical miles [6,076 feet or 1.85 Km] per hour.)
1 Knot = 1.85 Km/hr. Warm air (lower barometric pressure) always moves toward colder, denser air (higher barometric pressure). The direction of the wind can change due changes in temperature, microclimates (localized weather), changes in the seasons, the arrival of larger storm fronts, or, on the coast, the change from day to night. A drastic change in wind direction could mean the arrival of a storm front.
